The biggest storyline heading into Game 1 is health. Philadelphia star Joel Embiid is currently out with an abdominal issue, putting more pressure on Tyrese Maxey, who just scored 31 points in the play-in clincher to push the Sixers into this series.

Boston, meanwhile, enters with momentum after a strong finish to the regular season and boasts one of the league’s most balanced rosters, led by and Jaylen Brown. With home-court advantage and superior depth, the Celtics are clear favorites, but given the history between these teams and the Sixers’ recent surge, this opener still carries upset potential, making for a physical, high-intensity start to the series.
